i think you mean elliptical, and i believe it was Johannes keplar
It is believed that Nicolaus Copernicus first proposed the heliocentric theory.
The ellipses were discovered in the 17th century by one Johannes Kepler. Johannes Kepler discovered that the orbits along which the planets travel around the Sun are ellipses with the Sun at one focus, in his first law of planetary motion.
Johannes Kepler replaced circles with ellipses in the heliocentric model of the universe.
The astronomer who discovered that planets orbit the Sun in elliptical paths is Johannes Kepler. His work, particularly the first of his three laws of planetary motion, established that planets move in ellipses with the Sun at one focus. This groundbreaking discovery was published in his work "Astronomia Nova" in 1609. Kepler's laws fundamentally changed our understanding of celestial mechanics.
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.
Johannes Kepler was the person who first showed that planetary orbits are ellipses. His work, published in 1609, is known as Kepler's first law of planetary motion.

No,First, the Moon goes round the Earth, not the other war round.Second, all orbits are ellipses not circles.

In 1832, by an astronomer John H W Herschel, while presenting a paper "on the investigation of the Orbits of Revolving Double Stars"
Planets remain almost perfectly spherical as they move around the sun. The paths they follow are ellipses, with the sun at one focus of each ellipse.
None of Hypatia's works survived. We do not know what she discovered.

Tycho was the first astronomer to make measurements of enough accuracy to show that the older theories were producing errors in the planets' positions. The difference between an ellipse and the old model of a circle and epicycle, which gives a circle with the Sun off-centre, was so small that it needed high accuracy to notice the difference. Planets' orbits have an extremely small difference between the major and minor axes of the ellipses.
